For a prepper: better than 2L Soda - 3L stackable Arrowhead water:
I LIKE those. Water storage is getting to be a hassle as we're up to 4 1/2 gallons per day. Stacking would make things that much easier.
My wife prefers her tea made with non-tap water, so we have been buying those 3L containers, and I have been using them for emergency water storage. Indeed, they are much better than 2L bottles.
My hubby is addicted to Diet Coke, so we get a couple of 2L bottles every week, which I use for water storage. 3L sounds so much better, so I'm going to go looking for those. Thanks for the tip, guys~!
